Example A

8. Recheck the tapered roller bearing preload.
9. How to select the correct thrust shim.

• 1)Compare the tapered roller bearing preload you get with the thrust shim that was removed, with the specified preload of 1.4 – 2.6 Nm .
• 2)If your measured tapered roller bearing preload is less than specified, subtract yours from the specified.

If yours is more than specified, subtract the specified from your measurement.

For example, with a 2.17 mm thrust shim:

Example A

Specified torque = 2.6 Nm
Your measurement = 0.6 Nm
Subtract 0.6 Nm from 2.6 Nm = 2.0 Nm less

Example B

Your measurement = 3.4 Nm
Specified torque = 2.6 Nm
Subtract 2.6 Nm from 3.4 Nm = 0.8 Nm more

• 3)Each shim size up or down from standard makes about 0.3 – 0.4 Nm difference in tapered roller bearing preload.
• In example A, your measured tapered roller bearing preload was 2 Nm less than standard, so you need a thrust shim five sizes thicker than standard – try the 2.32 mm thrust shim and recheck.
• In example B, yours was 0.8 Nm more than standard, so you need a thrust shim two sizes thinner – try the 2.11 mm thrust shim and recheck.

10. After adjusting the tapered roller bearing preload, assemble the transmission and install the transmission housing, see MANUAL GEARBOX.

Torque

10 x 1.25 mm = 45 Nm.
8 x 1.25 mm = 28 Nm.

11. Rotate the differential assembly in both directions to seat the tapered roller bearings.
